Linked symbol samples and unexpected file format

I downloaded some of the free linked symbols from the website and added them to the symbol directory as the instructions say to do. The symbol I added shows up under the project symbols but not in the symbol library when I try to add a new symbol. If I click on the one in the project library I get an error saying unexpected file format. I have tried a dozen different symbols and they all do the same thing. Can anyone shed any light on this as I am stumped.

To elaborate. I add the downloaded symbol to the symbol library under the application install directory. It shows up as blank like its not there but the name is there. If I add it to my project symbol library the symbol name shows up in the project symbols. Either way I do it I get the unexpected file format when trying to use the symbol
